Introduction
The STCSLAC12036 surge suppressor is specically designed for electronic instruments used by the water/
wastewater industries. It combines hybrid AC power protection and signal line protection in a NEMA-4X
polycarbonate enclosure.
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E,
NOM-029-STPS or CSA Z462.
• This equipment must only be installed and serviced by qualied electrical personnel.
• Turn o all power supplying this equipment before working on or inside equipment.
• Always use a properly rated voltage sensing device to conrm power is o.
• Replace all devices, doors and covers before turning on power to this equipment.
• This equipment must be eectively grounded per all applicable codes. Use an equipment-grounding conductor to
connect this equipment to the power system ground.
• Conrm that the Surge Protective Device voltage rating on the module or nameplate label is not less than the
operating voltage.
• On DC signal line protection do not apply more than 150mA
• On AC line protection do not apply more than 15 Amps of continuous current.
Failure to follow these instructions will result in death or serious injury.
WARNING: This product can expose you to chemicals including DINP, which is known to the State of
California to cause cancer, and DIDP which is known to the State of California to cause birth defects or other
reproductive harm. For more information go to: www.P65Warnings.ca.gov.
NOTICE
LOSS OF SURGE SUPPRESSION
• Make certain that Surge Protective Device is disconnected from the circuit it is protecting before conducting high
potential insulation testing.
Failure to follow these instructions can result in equipment damage.

Installation
1. Turn off all power supplying this equipment before working on or inside equipment.
2. Conrm that the unit has the same voltage rating and conguration as the power system voltage and
power system voltage to which it will be connected.
For AC Power Connections:
a. Connect AC Power as Marked on Case using #14 - #12 AWG wire (L, N, G). Torque to
12 lb-in (1.35 N-m).
b. Keep 120 VAC Power feed separate from Low Voltage signal feed.
For Signal Line Connections:
a. Connect GND Terminal to Local Ground using #12 AWG wire minimum. Torque to 12 lb-in (1.35 N-m).
b. L1 and L2 – Connect for Signal Pair #1.
c. L3 and L4 – Connect for Signal Pair #2.
d. Terminals accept #24 - #14 AWG wire, torque to 3.47 lb-in (0.4 N-m).
3. Replace the barrier, cover/door and/or trim to the equipment.
4. Equipment may be re-energized after all the above steps are complete.
